PAPER MACHINE REEL 7 Filed Oct. 27, 1961 2 Sheets-Sheet 2 United States Patent 3,103,321 PAPER MACHINE REEL Ronald F. Jilelr, Appleton, Wis., assignor to Valley Iron Works Corporation, Appleton, Wis. Filed Oct. 27, 1961, Ser. No. 148,207 4 Claims. (Cl. 24265) This invention relates to continuous winding machines for paper and other web material. More particularly, the invention relates to a winding machine with a simple carriage and carriage way arrangement that Stops the rotation and movement of a Wound mandrel, and promptly returns the carriage adjacent the driving drum to be in position to guide the mandrel being wound in the primary arms by bypassing the carriage under the wound mandrel.

Modern paper mills have generally adopted a winding machine utilizing a driving drum and reels of the uniform speed type. The machine is provided with primary arms that support .a reel mandrel while the roll is starting thereon and then transfers the mandrel to secondary supports having a reel way and guiding carriages associated therewith to complete the Winding operation.

One of the problems encountered in previous continuous winding machines is the delay in transferring the completed roll from the carriage in order to return the carriage adjacent the driving drum to be in position to receive the next started mandrel from the primary arms.

It has been proposed to avoid this delay by utilizing a disappearing rear horn on the carriage thus permitting the mandrel to roll free under gravity from the carriage when the winding operation is complete. However, the inertia of the rotating paper roll on the mandrel did not permit the reel to move away from the carriage uniformly and, thus, the mandrel tended to cock as it would roll away from the carriage.

It is, therefore, an object of this invention to provide -a winding machine having a carriage to guide the reel along the ways and upon completion of the winding operation the carriage and reel are quickly moved to position remote from the driving drum where the rotation of the wound reel is quickly stopped and the ways are provided with means to pass the carriage front horn under the reel, returning the carriage adjacent the driving drum to be in position for guiding the newly started reel from the primary arms.

It is another object of this invention to provide a new and novel secondary support arrangement for E3. paper windin g machine.

Another object of this invention is to provide a movable carriage that guides the paper reel uniformly along the length of the secondary support until winding is completed whereupon the reel is braked to a stop and remains at rest while the carriage is returned.

Another object of this invention is to provide a carriage on the secondary support that controls the movement of the completed reel until braked to a stop before releasing the roll from the carriage horns.

Another object of this invention is to provide a simpleview of 3,103,321 Patented Sept. 10, 1963 FIG. 5 is a fragmentary view in side elevation to show the carriage in the bypass portion;

FIG. 6 is an enlarged fragmentary sectional view of FIG. 1 along the lines VIV'I.

Referring to the drawings, FIG. 1 discloses a continuous winding machine for receiving finished paper 19 from the mill and winding it into rolls. The winding machine generally includes "a base 10 for supporting a mandrel 15 upon which the paper 19 is rolled. Before entering into a detailed description, the general operation will be briefly explained. The mandrel 15 is placed upon the bifurcated ends of primary support arms 17. The arms 17 are rotated bout a rotating drum 12 until the mandrel 15 contacts the drum 12. Drum 12 brings the mandrel up to high speed rotation at which point the paper 19 is broken by an air jet and directed around the bare mandrel to start a new roll of paper. Meanwhile the completed roll of paper 81 is moved away from the drum 12 by a carriage 14 and directed against a brake 18 to stop its rotation. After stopping, the roll 81 is lifted away by an overhead crane, not shown. During the removal of the finished roll 81, the new roll, which is building, is gradually lowered to the guide ways 25. The carriage 14 returns to its original position with the spring biased horn 62 passing under the new roll.

The winding machine structure will now be described in more detail. As shown in FIGS. 1, 2 and 6, the mandrel supporting means comprise a pair of spaced parallel supports 10, journal housings 11 mounted on the rear ends of supports 10, and a mandrel driving drum 12 extending between and journaled in journal housings 11. Suitable means (not shown) are provided to drive drum 12 at a speed constant with the paper web speed.

Each support 10 includes spaced parallel inner and outer side walls 20, 21 having inwardly facing C-shaped portions 22 defined at the uppermost portion of each side wall 20, 21 that defines ways 13 therebetween. The inner side wall 20 is provided with an upward extending flange 25 defining a rail 24. The rails 24 together form a track for supporting a mandrel 15 during the winding operation.

Ways 13 include bypass means, the purpose of which will be explained later. As shown in FIGS. 1 and 5, the bypass means comprises a spur 77 having a depending portion 78 and an upward portion 80. Depending portion 78 communicates with ways 13 remote from drum 12 and is slightly enlarged relative to ways 13.

The upward portion is provided with switch means 79 that provides one way communication with ways 13. Switch means 79 comprises a portion of Ways 13 and is adapted to open when an upward force is exerted against switch means 79. Biasing means (not shown) are associated with switch means 79 to maintain switch means 79 in a normally closed position.

The preferred type of reel or mandrel for use with the winding machine of this invention includes a core having a winding surface for receiving a continuous web, braking surfacesfor stopping the rotation of a wound mandrel and a bearing housing for supporting the core winding surface for rotation relative to the bearing housing. Referring to FIG. 4, mandrel 15 comprises a shaft 32 having a centrally disposed winding surface 33 upon which the continuous web is wound, bearing housings 30 rotata'bly supported on shaft 32 adjacent the ends of winding surfaces 33, and braking surfaces 34 defined at outboard ends of shaft 32 and integrally associated therewith. 'Ihe inboard portion of each bearing housing 30 has a configuration that defines a flanged wheel 27 for cooperation with rail members 24 and maintains the mandrel 15 in alignment during the winding operation.

To control the movement of each mandrel 15 away from drum 12 a carriage 14 is provided for each support 10. Each carriage 14 has front and rear guide members, mandrel restraining members, and means to actuate the carriage toward and away from drum 12.

As shown in FIGS. 3, 4 and 6, each carriage includes a chassis having a top member 56 and side members 57 depending downwardly from top member 56. The front and rear guide members 58, 59 are preferably of low friction design such as cam rollers and are rotatably mounted to the outboard portions of side members 57. Guide members 58, 59 are disposed in ways 13 and guide the carriage 14 along supports 10. Thus, the pressure of mandrel 15 against drum 12 is not adversely affected by friction losses generated by the carriage guide members 58, 59.

Carriage 14 is provided with mandrel restraining members such as front and rear horns 61 62. The front horn 60 is rigidly mounted on the front portion of top member 56 and carries a roller 61 for engagement with p the hereinafter described mandrel bearing housing 30.

The rear horn 62 is foldable and adapted to be capable of exerting a linear force in a single direction. Thus, in moving the carriage 14 toward drum 12, the horn 62 upon encountering an object such as mandrel bearing housing 30, will collapse and pass under the object. The foregoing is accomplished by providing a shaft 63 extending between carriage side members 57 adjacent the rear portion of carriage 14. Horn 62 is pivotally mounted on shaft 63 and includes yieldable biasing means such as spring 64 that returns horn 62 to a raised position after being collapsed and an arcuate surface 75, the purpose of which will be explained later.

Power means 16 actuate carriages 14 toward and from driving drum 12 and are disposed between the side walls 20, 21 of each frame 10. As shown in FIG. 1, each power means 16 comprises a fluid motor such as a double acting fluid pressure cylinder 69 having ports 69' operatively connected to the fluid pressure control means (not shown). Cylinder 69 is pivotally mounted in frame 10 at '70 and is operatively connected to carriage 14 by lever 67 and tie rod 68. Lever 67 is journaled on shaft 66 and extends upward from shaft 66. At the upper end of lever 67 tie rod 68 pivotally connects lever 67 to carriage 14 by pins 71, 72, respectively. Lever 67 is pivotally connected to the piston rod 73 by pin 74 intermediate shaft 66 and pin 71 to complete the linkage. Thus, pressure fluid in hydraulic cylinder 69 selectively moves lever arm 67 to the left or to the right, moving carriage 14- toward or from driving drum 12.

Each support 10 is provided with braking means for stopping the rotation and movement of a wound mandrel. As shown in FIG. 5, the support braking means comprises a braking member 18 mounted on support 111 remote from drum 12 having an arcuate surface adapted to cooperate with the mandrel braking surfaces 34.

Since the winding operation is continuous, means are required to start the winding of the paper web on an empty mandrel 15 Without stopping the machine. The mandrel starting means are disposed at the rearward ends of each support 10 for cooperation with driving drum 12 and include an upward extending bracket mounted on the journal housing 11 and primary arms 17 rotatably journaled in journal housing 11 coaxial to drum 12.

The upward extending bracket includes a mandrel bearing housing stop member 28 and a slide member 29. The stop member 28 is provided to guide the mandrel 15 into the primary arm 17 during the loading operation. The slide member 29 is provided to maintain an empty mandrel 15 in an inoperative position until rotation of the primary arm 17 causes the mandrel 15 to move off slide 29 and into engagement with driving drum 12.

The primary arms 17 are bifurcated at the radially outer portions and define open ended bearing yokes 36 for receiving mandrel bearing housings 30. Spaced parallel brackets 37 are mounted to each primary arm 17 and extend tangentially rearward of yoke 36. A C-shaped arm 38 is pivotally mounted between each pair of parallel brackets 37 remote from primary arms 17, as by pin 39.

A double acting fluid pressure cylinder 41 at the end thereof is pivotally connected to trunnion 42 mounted on each primary arm 17 by pin 43 and the other end is pivotally attached to C-shaped arm 38 by pin 45. Pressure fluid is selectively directed to cylinder ports 41' by the pressure control means (not shown) to shift the c-shaned arms 38 between inner and outer limit positions.

C-shaped arms 38 in an inner limit position secure mandrel bearing housing 30 in the yoke 36 of each pri mary arm 17. C-shaped arms 33 in an outer limit position (not shown) permit primary arm yokes 36 to be loaded when arms 17 are in the position shown in FIG. 1, or will release mandrel 15 from yokes 36 as the paper roll 81 increases in diameter and moves reel 15 away from drum 12 along rails 2-1 when arms 17 are rotated to an unloading position (not shown).

Primary arms 17 are rotatably actuated by a double acting fluid pressure cylinder 47 having ports 47 operatively associated with the pressure control means (not shown). A shaft 48 extends between and is journaled for rotation in frames 10. Levers 49 and 511 are mounted on shaft 48 for rotation therewith. A tie rod '51 is pivotaily connected to a second trunnion 52 mounted on each primary arm 17 and to lever 50 by pins 53 and 54, respectively. The piston rod 55 of cylinder 47 is pivotally connected to lever 49 to complete the linkage. Thus, pressure fluid extending cylinder 47 causes primary arms 17 to pivot downwardly to a mandrel transfer position. Pressure fluid contracting cylinder 47 returns arms 17 to a starting position ready to receive a mandrel 15 and begin a new reel cycle. The actual release or locking of a mandrel 15 in the primary arm yokes 36 depends upon the position of the C-shaped members 38.

During the major portion of the winding operation, the mandrel 15 is supported on rails 24- and guided thereon by carriage 14. The bias of the disappearing rear horn 62 centers the mandrel bearing housing 31} between the front born 60 and the arcuate surface 75 of rear horn 62. The arcuate surface 75 of rear horn 62 provides a wedging force against front horn 6th to maintain the mandrel centered and also accommodates dimensional variations that may be present in the mandrel bearing housing 30. Winding pressure between the driving drum 12 and the reel mandrel 15 is a function of the fluid pressure in the double acting cylinders 69 and is controllable by the pressure fluid control means (not shown). When the mandrel 15 is fully wound, the web 19 is severed and simultaneously star-ted on the mandrel 15 in primary arms 17. Fluid pressure is applied to cylinder 69 to cause carriage 14 to move to the left away from driving drum 12. This causes the mandrel braking surface portion 3 to engage brakes 18 and stop the rotation of the completed roll.

As the carriage 14 guides mandrel braking surface 3 1 within one-eighth inch of the brake 18, the front cam rollers 58 fall into the depending portion 78 of bypass spur .77. The depending portion'78 of spur 77 being slightly oversize relative to ways 13 when the mandrel braking surface 34 contacts brake 18, the carriage front guides 58 will not bind in spur portion 7 8 and remain free.

The rotation of the fully wound mandrel 15 being halted, the pressure fluid directed to the cylinder 69 is reversed moving carriage 14 to the right and pulling the guides 58 along spur 77 toward the driving drum '12. As the guides 58 moves upward along spur portion and approach ways 13, the hinged portion 79 is engaged by guides 58. The hinged portion 79 is actuated upward by guides 58 and provides egress for guides 58 from spur 77 to re-enter ways 13.

The carriage 14 continues its movement toward driving drum 12 where the new mandrel 15 retained in primary arms 17 is winding web 19 on rails 24. The foldable rear horn 62 of carriage 12 is forced under mandrel bearing housing 30 and the spring 64 forces the horn 62 upward wedging mandrel bearing housing 30 between the carriage horns '60, 62. As the wound web 81 increases in size, the carriage 14 moves to the left out of the primary arm yokes 36 permitting the primary arm 17 to rotate upward into a mandrel loading position above the driving drum 12. A mandrel 17 is placed in the primary arm yokes 36 and the cycle is repeated. When the mandrel 15 on the rails 24 is wound to a desired diameter, the web 19 is severed and started on the empty mandrel 15 in the primary arms 17 as already described.
